This invention relatos to a toilet bowl and has for an object to provide an improved toilet bowl which can carry and discharge all the water coming from the flush tank in the event that the trap of the bowl should become clogged.

A further object of this invention is to provide a toilet bowl which cannot overflow and discharge its contents on the floor of the bathroom in the event that the trap of the bowl should become clogged by any obstructions.

A further object of this invention is to provide a toilet bowl with a plurality of by-passes capable of conducting the entire water to the soil pipe in case the trap of the bowl should be obstructed, which by-passes, however, will ordinarily not conduct any water, or only a very small portion thereof, so long as the bowl trap is in good working condition.

A further object of by-passes in a toilet bowl for carrying the water around the bowl trap, which by-passes have a greater total arca than the area of the trap.

Still a further object of this invention is to provide a clean out at the crown of the bowl trap making it possible to remove any obstruction and clean out the bowl trap without the necessity of removing the bowl from the floor.

With the foregoing and other objects in view, as will hereinaiter become apparent, this invention comprises the constructions, combinations and arrangements of parts, hereinafter set forth, disclosed and shown on the accompanying drawing. In this drawing,

Figure 1 is a vertical sectional view of the improved water closet bowl,

Figure 2 is a vertical view of the lay-pass for the toilet bowl,

Figure 3 is a. rear view of the bowl, partly broken away to show one of the by-passes. and

Figure 4 is a sectional view taken on the line 4-4 of Figure 2.

There is shown at ll] the toilet bowl constituting this invention. This bowl l0 has a. water inlet H adapted to be connected up to a supply of. water such as a flushing tank or water pressure line, or the like.

A by-pass 5 also connected to the inlet l l leads directly to the trap l6 discharging therein through a jet opening I'l. This jet opening l'l assists in forcing the contents of the trap IB to the outlet leg IB of the trap and to the bowl outlet la. It often happens that the trap IG of the toilet may become clogged or stuffed by some obstruction, prevnting the flow of water therethrough. In the usual toilet bowl when this happens the this invention is to provide water level 53 flows over the toilet bowl onto the floor of the lavatory or bathroom soiling and damaging the floor as well as penetrating to the ceiling below causing additional damage.

In order to prevent this damage this inventon provides a pair of by-passes situated on either side of the bowl trap Iii and leading from a bypass inlet 26 located in the bowl M to a by-pass outlet 2II located in the toilet bowl outlet IS. It will be further observed that the inlet by-pass leg 25 is substantially parallel in direction to the inlet leg of the trap HS and that the outlet bypass leg 2i is substantially parallel to the outlet leg of the trap E6. Also that the discharge outlet of the by-pass outlet 2! lies vertically above at least in part, over the bowl outlet le. As will be apparent from Figure 3, the side walls of the main trap are vertically disposed and the inlet openings leading to the by-pass inlet 20 are vertica]. As a result of this construction the excrement cannot lodge in and block the opening as it washes back and forth when the water first begins to fiush the bowl and before there is sufficient pressure to flush it. Furthermore, if the trap IS becomes blocked the flow of water does not have to reverse itself, but instead is taken by the inlet by-pass Zi] in substantially the same direction as the inlet leg of trap IES, and then discharges at the end of the outlet passage 25 so as to fall directly into the bowl outlet I9 and not be subject to further obstructio-ns or corners, thereby insuring against overfiow. These by-passes 22, it will be observed, are likewise in the form of a trap or inverted U, so that they will not lower the level of the water l3 in the toilet bowl I4.

It will be further observed that these by-passes 22 are out of the direct line of flow of the water 3 through the bowl M to the trap IG on its way to the outlet |9, and further, that the combined cross sectional arca of these two by-passes is greater than the cross sectional arca of the trap IS. With this construction the water I3 will flow through the trap IS to the down leg l8 and outlet l9 so long as the trap l6 is unobstructed. Should 7 the trap |6 become obstructed for any reason, then the water which would ordnarily overfiow the sides of the bowl to damage the floor, will instead be diverted through the by-pass inlet 20 through the by-pass 22 and to their by-pass outlets 2! leading to the bowl outlet E9, thus by-passing the water about the obstruction and preventing the overflow. It will be further noted that the by-passes as located on opposite sides of the trap l8 do not materially increase the bulk of the toilet and do not require any extra space in the room not already occupied by the toilet bowl.

In order to remove the obstruction that may be present in the trap ES, a clean-out 23 is located in the crown 2; of the trap lt. This clean-out 23, as Will be observed, includes an aperture 25 of suficient size to permit the entrance of fishing tools for removing the obstruction. This aperture 25 is normally closed by a plug 25 carried by the clean-out closure member 23, the plug 25 being preferably of resilient sealing material such as soft rubber, so as to prevent the escape of any noxious gases coming into the trap E6 from the soil pipe connected to the outlet H9.

As a result of this invention the by-passes 22 prevent the overfiow of the toilet water i3 onto the floor of the toilet room. The by-pass i5 assists in emptying the trap i t, while th clean-out 23 permits any obstruction in the trap ES to be removed without the necessity of taking up the bowl 58 or disturbing the plumbing.

The novel features and the operation of this device Will be apparent from the foregoing description. While the device has been' shown and the structure described in detail, it is obvious this is not to be considered limited to the exact form disclosed and that changes may be made therein within the scope of what is ciaimed without departing from the spirit of the invention.

Having thus set forth and disclosed the nature of this invention, what is olaimed is:

having a bowl bottom, a bowl V. c narge out et, an inverted U trap connecting said bowl portion to said bowl discharge outlet for dis charge of the bowl contents, and bypass means leading from the bowl portion directly to As being in the form of an inverted U trap, the iret and outlet legs of said by-pass U being substantialiy said bowl discharge outlet, said by-pass mean leading frorn the bowl portion directly to said.

bowl discharge outlet, said bypass means being in the form of an inverted U trap, the up-leg and down-leg of said bypass U being substantially parallel to the inlet and outlet legs of said bowl U trap, and the discharge outlet of the bypass dcWn-leg being vertically over said bowl discharge outlet, said by-pass up-leg having an in1et in the vertically disposed side walls of the main trap.

3. As an article of manufacture, a toiiet bowl having a bowl bottom, a bowl discharge outlet, a main inverted U trap connecting said bowl por tion to said bowl discharge outlet for normal dis charge of the bowl contents, said main trap having vertically clisposed side Walls and bypass means leading from the bowl portion directly to said bowl discharge outlet, said by-pass means being in the form of an inverted U trap, the upleg and down-leg of said by-pass U being substantially parallel to the inlet and outlet legs of said bowl U trap, and the discharge outlet of the by-pass downleg being vertically over said bowl discharge outlet, said oy-pass up-leg having an inlet in the vertieaily disposed side walls of the main trap, said by-pass means being in the form of a pair of bypass passages located on each side of the bowl U trap.
